One of the wondrous and unique characteristics of plant development is the ability to produce organs throughout life and flexibly react to internal and external cues. Two plants, even if genetically identical, are different in the number and form of their organs. In the Ori group, we are interested in the mechanisms that underlie the plasticity of plant development and patterning.
Leaf development beautifully exemplifies developmental plasticity, leading to enormous variability in shape and size, which is particularly evident in compound leaves. In addition, the leaf is relatively tolerant to developmental aberrations, making it an attractive system to study developmental principles. We study compound leaf, flower and fruit development in tomato using genetic, developmental and molecular tools.
